## About the role

The Foundation Agents team stewards the long-horizon agents powering the Fieldguide AI platform.

- You're strong in the backend and comfortable owning platform-level systems
- You're motivated by long-horizon agents that do real work in production
- You multiply the people around you, not just your own output
- 1+ years working specifically on agents
